CHRONIC OBSTRUCTIVE PULMONARY DISEASE Familial aggregation of FEF25–75 and FEF25–75/FVC in families with severe, early onset COPD
Background: The Boston Early-Onset COPD study showed that current or ex-smoking first degree relatives of severe early onset COPD probands have significantly lower forced expiratory volume in 1 second (FEV1) and FEV1/forced vital capacity (FVC) values than current or ex-smoking control subjects, which suggests the existence of genetic risk factors for the development of COPD in response to ciga...
متن کاملAsthma diagnosis and treatment – 1002. FEF25-75%: a more sensitive indicator in the early detection of asthma
Background Spirometry is widely regarded as a clinically invaluable measurement method that is of genuine recommend for the diagnosis and management of asthmatic patients. FEV-1 and FEV1/FVC are vastly perceived as asthma severity and control assessment indices, according to the present clinical guidelines. Since FEV-1 index is chiefly within normal ranges even in the most severe cases, the cer...
متن کاملp63 is more sensitive and specific than 34βE12 to differentiate adenocarcinoma of prostate from cancer mimickers
Objective(s): Prostate cancer is the world’s leading cause of cancer and the second cause of cancer-related death in men after lung cancer. Differentiation of prostate adenocarcinoma from benign prostate lesions and hyperplasia sometimes cannot be done on the basis of morphologic findings. Considering the fact that in the prostate adenocarcinoma there is no basal cell layer, basal cell markers ...
متن کاملKeratin 13 is a more specific marker of conjunctival epithelium than keratin 19
Introduction To evaluate the expression patterns of cytokeratin (K) 12, 13, and 19 in normal epithelium of the human ocular surface to determine whether K13 could be used as a marker for conjunctival epithelium. Methods: Total RNA was isolated from the human conjunctiva and central cornea. Those transcripts that had threefolds or higher expression levels in the conjunctiva than the cornea wer...
متن کاملRole of Methacholine PC20 in FEF25-75% for the Diagnosis of Bronchial Asthma
Background: The methacholine bronchial provocation test is a useful tool for evaluating asthma in patients with normal or near normal baseline lung function. However, the sensitivity of this test is 82∼92% at most. The purpose of this study is to evaluate the clinical usefulness of FEF25-75% in identification of airway hyperresponsiveness in patients with suspected asthmatic symptoms. Methods: ...
